Thirty seven years after it was released, horror movie 'The Exorcist' has been voted as "most disturbing" film of all time.

The 1973 film directed by William Friedkin, adapted from the 1971 novel of the same name by William Peter Blatty is based on the exorcism case of Robbie Mannheim and is the tale of the demonic possession of a child, which featured Linda Blair as the kid spewing green slime.
